Description
Technical Field
[0001] This utility model relates to the field of positioning vehicle technology, specifically a positioning vehicle drive gear anti-fall detection device. Background Technology
[0002] A tippler system is a highly specialized bulk material unloading system used for unloading bulk materials loaded on trains. Tippler coal unloading systems offer high unloading efficiency, minimal damage to vehicles, improved working conditions for operators, and facilitate automated mechanical control. With the continuous development of the national economy, the demand for bulk materials such as coal, coke, and ore transported by train has increased significantly due to the construction of thermal power plants, smelters, cement plants, ports, and mines. Large-scale modern enterprises have widely adopted tippler unloading systems. Since a tippler can only unload 1-4 cars at a time, auxiliary mechanical equipment (such as pushers and positioning cars) is needed to advance and position the open wagons during the unloading process to ensure continuous unloading operations.
[0003] The current positioning vehicle drive device consists of a drive motor, reducer, drive gear, and meshing rack. Since the positioning vehicle needs to tow nearly 10,000 tons of wagons during operation, the positioning vehicle drive gear often bears a lot of torque. Once the fixing bolt breaks, it will cause the positioning vehicle drive gear to fall off. Since the positioning vehicle is composed of multiple drive devices, the fall of a single gear will not affect the operation of the positioning vehicle. However, the fallen gear will be dragged by the positioning vehicle at the bottom, causing damage to the positioning vehicle's ground rack fixing device. To address this, we propose a positioning vehicle drive gear anti-fall detection device. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning vehicle drive gear anti-fall detection device to solve the problem in the prior art that the gear that falls off the positioning vehicle will be dragged by the positioning vehicle at the bottom, causing damage to the positioning vehicle ground rack fixing device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning vehicle drive gear anti-fall detection device, comprising two fixed plates, an adjustment mechanism provided between the two fixed plates, a connecting plate fixed to the top edge of the fixed plates, a hanging ear fixed to one side of one of the connecting plates, a steel wire rope connected to the outside of the hanging ear, a magnet fixed to one end of the steel wire rope, a proximity switch fixed through one side of the other connecting plate, and an iron ring fixed to the other side of the other connecting plate.
[0006] Preferably, the signal output terminal of the proximity switch is connected to the PLC controller of the positioning vehicle. When the magnet separates from the proximity switch, the signal is transmitted to the PLC controller to control the positioning vehicle to stop. The end diameter of the proximity switch is smaller than the inner diameter of the iron ring.
[0007] Preferably, the connecting plate is fixed to the bottom of the positioning vehicle, and the wire rope is located at the bottom of the driving gear of the positioning vehicle, so that when the gear falls off, the wire rope can be pressed down to separate the magnet from the iron ring.
[0008] Preferably, the adjustment mechanism includes sliding cavities symmetrically opened on one side of the fixed plate, with a limit rod sliding inside the sliding cavity, and a threaded cavity opened in the middle of one side of the fixed plate, with a bidirectional screw threaded inside the threaded cavity, and a knob provided in the middle of the outer side of the bidirectional screw.
[0009] Preferably, the outer side of the knob is provided with anti-slip texture to prevent slippage during rotation, and both ends of the limiting rod are provided with baffles, which are located inside the sliding cavity to prevent the limiting rod from disengaging from the sliding cavity.
[0010] Preferably, a movable groove is provided through the bottom of one side of the connecting plate, and a T-shaped block slides inside the movable groove. A buffer spring is fixed to the bottom of the T-shaped block. An inclined plate is fixed to one side of one T-shaped block, and a storage shell is fixed to one side of the other T-shaped block. When the gear falls off, it falls on the inclined plate and the storage shell, which guides the gear and keeps it away from the rack on the ground. The buffer spring also cushions the impact on the device during the fall.
[0011] Preferably, the storage shell is installed at an angle, and the inclined plate slides inside the storage shell. An anti-detachment plate is fixed to one side of the inclined plate, and the anti-detachment plate is located inside the storage shell to prevent the inclined plate from detaching from the storage shell. The buffer spring is fixed to the top of the fixed plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this application, a connecting plate is welded to the bottom of the positioning vehicle, and then a steel wire rope is tied to the hanging lug, causing the magnet to attract the iron ring. This keeps the steel wire rope taut at the bottom of the driving gear of the positioning vehicle. When the driving gear falls off, the steel wire rope is pressed down, causing it to move the magnet and separate it from the iron ring. A proximity switch detects the separation of the magnet and transmits a signal to the PLC controller of the positioning vehicle, stopping the positioning vehicle. This prevents the fallen gear from being dragged by the positioning vehicle and damaging the ground rack fixing device, ensuring the safety of the device. At the same time, when the gear falls off, it lands on the inclined plate and the storage shell, impacting them and causing the T-block to descend and compress the buffer spring. The deformation of the buffer spring reduces the impact on the device. Furthermore, the inclined plate and the storage shell are installed at an angle, so that when the gear falls off, it is far away from the rack, further preventing damage to the rack.
[0014] 2. In this application, the adjustment mechanism is used to adjust the position of the drive gear of the positioning vehicle before installation. By rotating the knob, the bidirectional screw is rotated and screwed into the threaded cavity. The limiting rod restricts the movement of the fixing plate on the limiting rod. When the knob is rotated, the fixing plate moves outside the bidirectional screw, thereby adjusting the spacing of the connecting plates. This makes it easy to adjust according to the number of drive gears of the positioning vehicle, so that the drive gear is located inside the connecting plate, which is convenient for use with various models of positioning vehicles.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for a positioning vehicle drive gear anti-fall detection device, which includes two fixing plates 100 and an adjustment mechanism 300 between the two fixing plates 100.
[0023] Please see Figure 2 , Figure 3 and Figure 5A connecting plate 200 is fixed to the top edge of the fixed plate 100. A hanging lug 210 is fixed to one side of one connecting plate 200, and a steel wire rope 220 is connected to the outside of the hanging lug 210. A magnet 230 is fixed to one end of the steel wire rope 220. A proximity switch 240 is fixed through one side of the other connecting plate 200, and an iron ring 250 is fixed to the other side of the other connecting plate 200. The signal output terminal of the proximity switch 240 is connected to the PLC controller of the positioning vehicle, and the end diameter of the proximity switch 240 is smaller than the inner diameter of the iron ring 250. The connecting plate 200 is fixed... The steel wire rope 220 is located at the bottom of the positioning vehicle's drive gear. A moving groove 400 is formed through one side of the bottom of the connecting plate 200. A T-shaped block 410 slides inside the moving groove 400. A buffer spring 420 is fixed to the bottom of the T-shaped block 410. A ramp 430 is fixed to one side of one T-shaped block 410, and a storage shell 440 is fixed to one side of the other T-shaped block 410. The storage shell 440 is installed at an angle, and the ramp 430 slides inside the storage shell 440. An anti-detachment plate is fixed to one side of the ramp 430, and the anti-detachment plate's displacement is controlled. Inside the housing 440, the buffer spring 420 is fixed to the top of the fixing plate 100. The connecting plate 200 is welded to the bottom of the positioning vehicle, and then the wire rope 220 is attached to the lug 210, causing the magnet 230 to attract the iron ring 250. This tautens the wire rope 220 at the bottom of the drive gear on the positioning vehicle. When the drive gear disengages, it presses down on the wire rope 220, causing it to move the magnet 230, separating it from the iron ring 250. The proximity switch 240 detects this separation and transmits a signal to... The PLC controller of the positioning vehicle stops the positioning vehicle from moving, preventing the detached gear from being dragged by the positioning vehicle and causing damage to the ground rack fixing device of the positioning vehicle, thus ensuring the safety of the device. At the same time, when the gear detaches, it falls on the inclined plate 430 and the storage shell 440, causing impact to the T-block 410, which compresses the buffer spring 420. The deformation of the buffer spring 420 reduces the impact on the device. In addition, the inclined plate 430 and the storage shell 440 are installed at an angle, so that when the gear detaches, it is far away from the rack, further preventing damage to the rack.
[0024] Please see Figure 4The adjusting mechanism 300 includes sliding cavities 310 symmetrically opened on one side of the fixed plate 100. A limit rod 320 slides inside the sliding cavity 310. A threaded cavity 330 is opened in the middle of one side of the fixed plate 100. A bidirectional screw 340 is screwed into the threaded cavity 330. A knob 350 is provided at the middle of the outer side of the bidirectional screw 340. Anti-slip texture is provided on the outer side of the knob 350. Baffles are provided at both ends of the limit rod 320, and the baffles are located inside the sliding cavity 310. Using the adjusting mechanism 300, before installation, according to... Adjusting the position of the drive gear of the positioning vehicle, rotating the knob 350 causes the bidirectional screw 340 to rotate. The bidirectional screw 340 is screwed into the threaded cavity 330. Using the limit rod 320 as a constraint, the fixing plate 100 moves on the limit rod 320. When the knob 350 is rotated, the fixing plate 100 moves outside the bidirectional screw 340, thereby adjusting the spacing of the connecting plate 200. This allows for adjustment based on the number of drive gears of the positioning vehicle, ensuring that the drive gears are located inside the connecting plate 200, making it suitable for various models of positioning vehicles.
[0025] In use, before installation, the spacing of the connecting plates 200 is adjusted according to the number of drive gears on the positioning vehicle. Rotating the knob 350 causes the bidirectional screw 340 to rotate, and the bidirectional screw 340 is screwed into the threaded cavity 330. Using the limiting rod 320, the fixing plate 100 moves on the limiting rod 320. When the knob 350 is rotated, the fixing plate 100 moves outside the bidirectional screw 340, thereby adjusting the spacing of the connecting plates 200 so that the drive gear is located inside the two connecting plates 200. Then, the connecting plates 200 are welded to the bottom of the positioning vehicle. The steel wire rope 220 is tied to the hanging lug 210, causing the magnet 230 to attract the iron ring 250, tautly positioning the steel wire rope 220 at the bottom of the drive gear on the positioning vehicle. When the drive gear detaches... The steel wire rope 220 is pressed down, causing it to move the magnet 230, separating it from the iron ring 250. The proximity switch 240 detects this separation and sends a signal to the positioning vehicle's PLC controller, stopping the vehicle and preventing the detached gear from being dragged and damaged by the ground rack fixing device. This ensures the safety of the device. Simultaneously, when the gear detaches, it lands on the inclined plate 430 and the storage shell 440, impacting them and causing the T-block 410 to descend, compressing the buffer spring 420. The deformation of the buffer spring 420 reduces the impact on the device. Furthermore, the inclined plate 430 and the storage shell 440 are installed at an angle, ensuring that the detached gear is away from the rack, further preventing damage to the rack.
